Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of switching over a pair of filters while reducing the overall size of the device, securing a high sealing property, and reducing a pressure loss caused when exhaust emission passes by the adoption of a poppet valve having a number of advantages. SOLUTION: An exhaust emission control device adopts a branch chamber 18, having a pair of valve seat walls 20a and 20b and an intermediate wall 21 surrounding an area between the pair of valve seat walls generally circularly, for a switch-over part 13 for introducing exhaust emission to a pair of filters 4a and 4b by the opening and closing of a pair of poppet valves 15a and 15b. Valve holes 22a and 22b open toward the center side of the branch chamber 18 are formed in each valve seat wall 20, and an exhaust pipe 1 of an engine is open in the intermediate wall 21 of the branch chamber 18 in the direction along the wall surface of the intermediate wall 21 so as to form the swirl flow of the exhaust emission in the branch chamber 18. By this swirl flow, the exhaust emission is introduced from the valve hole to the branch path while turning it around valve stems of the poppet valves 15a and 15b. Thus the exhaust emission is introduced from the outer peripheral sides of the poppet valves 15a and 15b, not from the front sides of the valve mushroom part of these valves, so as to reduce a pressure loss.

Abstract: PURPOSE:To secure the safety of a photographing operator by inhibiting the ejecting action of a recording medium even when an operation for ejecting the recording medium is executed when an operation switch except a switch related to the operation for ejecting the recording medium is operated. CONSTITUTION:A control part 34 controls stroboscopic light emission, stroboscopic turning off, etc., at photographing time according to mode setting by a stroboscope switch 25. Further, the control part 34 executes control so that self timer photographing action can be executed by operating a self timer switch 26 and that the ejecting action of a recording medium 3 can be executed by operating an ejecting switch 28. Further, when the switch 28 is erroneously operated while a switch except the switch 28 is operated, the control part 34 examines whether an inhibiting signal A exists or not and controls it so that the ejecting action can be inhibited when the signal A exists. Thus, it can be prevented that the ejecting operation is unexpectedly executed, and the medium jumps out and hits the operator on the face when the operator gets a camera ready and looks an object through the camera.
